| Abstract: | Summary The primary monoesters of diol compounds were formed exclusively in the reaction with vinyl acetate and Aspergillus niger lipase for 24~72 h. Various diol compounds which included 1,3-butanediol, 1,4-butanediol, 1,5-hexanediol, 1-phenyl-1,2-ethanediol, 1-phenyl-1,3-propanediol, 2, 3, or 4-hydroxybenzyl alcohol, methyl 2, 3-O-acetyl-D-glycopyranosides and phenyl 1-thio- -D-xylopyranoside have been examined and showed nearly 100% regioselectivity. |
